Abstract
The utility model relates to a solid-shaft head ball cage coupling device for the field of large impact force, continuous working non-ferrous metal, petroleum industries. A driving shaft and a driven shaft are respectively connected with a driving shaft flange and a driven shaft flange; a driving end outer ring and a driven end outer ring are respectively connected with a middle shaft by a keeping rack and a steel ball in the keeping rack; shaft heads at the two ends of the middle shaft are provided with many direct channels distributed in equal distance along the circle and the driving, driven end outer rings are respectively connected with the driving, driven shaft flanges; the end surfaces of the driving, driven end outer rings are respectively provided with sealing systems. The solid-shaft head ball cage coupling device has features of compact structure, saved design space; thorough elimination of the clearance of the spline pair, effectively reduced process difficulty, saved cost; high transmission precision; meanwhile elimination of the inner ring and the bolt for connecting the inner ring baffle and the middle spline shaft; shock resistance of the transmission shaft and long service life.
Description
Technical field
The utility model relates to machinery manufacturing technology field, particularly use on metallurgy, non-ferrous metal, the petroleum machinery ball cage coupling.
Background technique
As shown in Figure 2, existing ball cage coupling is mainly by driven shaft 22, driven shaft flange 23, the steel ball 26 that driven end outer ring 27 and driven end inner ring are 28, retainer 25, the screw 24 that connects driven end inner ring baffle plate and middle splined shaft, the sealing system 29 of end, driven end outer ring, middle splined shaft 30, the sealing system 31 of end, drive end outer ring, the steel ball 33 that drive end outer ring 35 and drive end inner ring are 34, retainer 32, the screw 38 that connects drive end inner ring baffle plate and middle splined shaft, driving shaft flange 36, driving shaft 37 compositions such as grade, wherein there are many to be oval or circular straight flute road on inner ring and the outer ring along the circumference cross section that evenly distributes, torque is through middle splined shaft spline, the inner ring spline, bear inner ring grooved railway, steel ball, two outer ring raceway transmit (or contrary direction), realize drive end and driven end transmission of power; The effect of retainer is that the steel ball group is on the equidistant point of transmission shaft, outer ring raceway constantly; The long-acting lubricating grease that sealing system inner filling ageing-resistant performance is good, contain extreme pressure agent.By the rolling of steel ball between the straight flute road, realize axially and the compensation of angle, and in the spatial design extreme angles, can be completely achieved constant speed.But there are matching gap in inner ring, middle splined shaft by the spline static connection between spline pair, difficulty of processing is big, takies the design space; And when the axial displacement of driven shaft 22 and driving shaft 37 was compression, screw 24 impacted driven shafts 22 and driving shafts 37 with screw 38, influences its life-span, simultaneously, makes the steel ball unbalance stress.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of integral shaft head shoot cage coupling, and inner ring and jack shaft are designed to one, and the cancellation spline pair to reduce difficulty of processing, improves the transmission shaft life-span.
For achieving the above object, the technical solution of the utility model is: driving shaft is connected with the driving shaft flange through connecting key, jack shaft drive end outer ring links to each other with the driving shaft flange through bolt and key, the drive end outer ring, many the straight flute roads that equidistantly distribute along circumference are arranged on the driven end outer ring, and steel ball one and steel ball two are housed between the jack shaft, steel ball one and steel ball two are installed in the window of retainer one and retainer two, sealing system is equipped with in the end of drive end outer ring and driven end outer ring, the driven end outer ring is connected with the driven shaft flange through bolt and key, be connected with flat key between driven shaft and the driven shaft flange, it is characterized in that: the spindle nose at jack shaft two ends has many straight flute roads that equidistantly distribute along circumference.
The utility model compared with prior art has the following advantages:
1, compact structure, the save design space;
2, thoroughly eliminate the gap of spline pair, effectively reduced difficulty of processing, saved cost;
3, transmission accuracy height simultaneously, has been cancelled the screw of inner ring and connection inner ring baffle plate and middle splined shaft, and transmission shaft is shock-resistant, long service life.

Embodiment
As shown in Figure 1, driving shaft 16 is connected with driving shaft flange 15 through connecting key, drive end outer ring 12 links to each other with driving shaft flange 15 through bolt and key, jack shaft 11, drive end outer ring 12, many the straight flute roads that equidistantly distribute along circumference are arranged on the driven end outer ring 3, between steel ball 1 and steel ball 24 are housed, steel ball 1 and steel ball 24 are installed in the window of retainer 1 and retainer 25, drive end outer ring 12, sealing system is equipped with in the end of driven end outer ring 3, and sealing system comprises gland 26 and gland 2 17, sealing gasket 27 and sealing gasket 1, seal closure 28 and seal closure 1, back-up ring 29 and back-up ring 1, clip 2 10 and clip 1; Driven end outer ring 3 is connected with driven shaft flange 2 through bolt and key, is connected with flat key between driven shaft 1 and the driven shaft flange 2.
When having axial displacement or angle to change during driven shaft 1 work, drive driven end outer ring 3 and be synchronized with the movement with driven shaft 1, steel ball 4 rolls in the raceway groove of driven end outer ring 3, and compensating axial displacement or angle change; Equally, when having axial displacement or angle to change during driving shaft 16 work, drive drive end outer ring 12 and be synchronized with the movement with driving shaft 16, steel ball 13 rolls in the raceway groove of drive end outer ring 12, and compensating axial displacement or angle change; The utility model is realized reliable transmission of power by driving shaft 16, jack shaft 11, driven shaft 1.
